A woman’s age has always been talked about when it comes to the success or failure of natural and in vitro fertilization (IVF) and how her biology affects this technique. A recent study goes a little further and suggests male age as one of the factors that also influence the outcome when a couple undergoes one of these treatments (see our previous article Male fertility also falls with age). The research, presented at the 33rd Annual Meeting of European Society of Human Reproduction and Embryology (ESHRE) in Geneva, evaluated 19,000 treatments in 7,753 couples between 2000 and 2014 and found a decrease in the success of these techniques directly related with male age (see HERE).

First research to calculate the cumulative live birth rate

The cases were divided into 4 age bands: women under 30, 30 to 35 years, 35 to 40 years and 40 to 42 years. The men were divided into the same age bands, to which an additional band was added, those who were aged 42 or over. This is the first research to calculate the cumulative live birth rate, divided by age groups of both men and women, “allowing both ages to be analyzed simultaneously”. “Our study found an independent effect of male age on the cumulative incidence of a live birth following IVF treatment”, according to the speech by Dr. Laura Dodge from the Beth Israel Deaconess Medical Centre and Harvard Medical School at the Congress.
